Verdict in brief
The NRC98DV and NRC111DV are the two larger NRC Series tankless water heaters: the NRC98DV fires 16,000 to 180,000 BTU/h at 0.90 UEF with 9.8 GPM in a 58 lb cabinet, while the NRC111DV reaches 199,900 BTU/h at 0.91 UEF with 11.1 GPM and weighs 68 lb in the same 24.2 x 18.3 x 9.4 in frame.

|---|---|---|
| Input, minimum | 16 MBH | 16 MBH |
| Input, maximum | 180 MBH | 199.9 MBH |
| Uniform Energy Factor (UEF) | 0.9 UEF | 0.91 UEF |

The NRC98DV and NRC111DV are the larger pair in Noritz's NRC Series, both indoor-only tankless water heaters with a 16,000 BTU/h minimum fire and the same 24.2 x 18.3 x 9.4 in cabinet. They are DHW-only appliances: no hydronic heating circuit.
The NRC111DV steps up on capacity and efficiency: 199,900 against 180,000 BTU/h of input, 11.1 against 9.8 GPM of flow and 0.91 against 0.90 UEF, at 68 against 58 lb. Temperature settings differ slightly too — the NRC98DV prints 115–140°F and the NRC111DV 100–140°F.
The NRC98DV page uses condensing language and lists a condensate overflow monitoring system; the NRC111DV page prints high-efficiency operation. Both run on 120 VAC and install indoors only. Sizing follows peak hot-water demand.
Noritz
The Noritz NRC98DV is a condensing tankless water heater in the NRC Series — a DHW-only appliance, not a boiler — firing 16,000 to 180,000 BTU/h with 9.8 GPM maximum flow at 0.9 UEF.
Noritz
The Noritz NRC111DV is a high-efficiency tankless water heater in the NRC Series — a DHW-only appliance, not a boiler — firing 16,000 to 199,900 BTU/h with 11.1 GPM maximum flow at 0.91 UEF.
Maximum input (180,000 against 199,900 BTU/h), maximum flow (9.8 against 11.1 GPM), UEF (0.90 against 0.91) and weight (58 against 68 lb). Minimum fire and cabinet are identical.
No. Both are residential tankless water heaters for domestic hot water only. Noritz's combi boiler is the NRCB.
The NRC111DV prints 100–140°F against the NRC98DV's 115–140°F, which gives the larger model a lower minimum setting.
A consultation includes a heat-loss review so the size is right the first time.
